CROSSING-GATE.

Specification of Letters Patent.

Patented Nov. 26, 1918.

Application filed February 16, 1918. Serial No. 217,615.

To all whom it may concern:

Be it known that I, JOHN O. OATMAN, a, citizen of the United States,residing at Tulsa, in the county of Tulsa and State of Oklahoma, haveinvented new and useful Improvements in Crossing-Gates, of which thefollowing is a specification.

This invention relates to new and useful improvements in crossing gatesand the principal object of the invention is to provide means forcontrolling traflic at street intersections.

Another object of the invention is to provide a series of barriers withmeans for lowering the barriers to close one street while simultaneouslyraising the barriers to open the cross street.

Other objects of the invention are to provide centrally located meansfor controlling all of the barriers, adjustable means for controllingthe length of the barriers, and means for easily rendering the barriersinoperative and for removing the devices from the street.

Another object of the invention is to provide a device of this characterwhich is simple and durable in construction, reliable and efficient inoperation and one which can be manufactured and placed upon the marketat a minimum cost.

The invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which Figure 1is an elevation showing one of the supporting posts for a pair of thebarriers or gates, one gate being in open or lowered position while theother gate is in raised position.

Fig. 2 is a view taken at right angles to Fig. 1.

Fig. 3 is a plan View of Fig. 1.

Fig. 4 is a plan view showing the arrangement of operating parts at theintersection of two streets. I

Fig. 5 illustrates the signaling means.

Fig. 6 is a sectional view of the operating means.

Fig. 7 is a section on line 77 of Fig. 6.

In these views A represents a street which is intersected by the crossstreet B and the drawing illustrates my improvements used for controllinthe pedestrian trafiic on the side-walks of these streets. It will ofcourse be understood that the invention may be used for closing thestreets proper with but little change in the construction thereof.

At each corner of the side-walks I locate a screw threaded socket 1,said socket being located below the level of the side-walk so as to beout of the way when the ates are removed. This socket receives t e screwthreaded end of a' post or upright 2 which carries a pair of gates, thegates bein located at right angles to each other. fiach gate is composedof a beam 3 pivoted to one end to the post adjacent the lower endthereof, a bar 4 having its upper end hooked and slidingly engaging aneye bolt 5 adjustably secured in the post. Said bar is pivotally securedto the central part of the beam 3 by a bolt 6 adjustably mounted in saidbeam and the other end of said bar is pivoted to a vertical bar 7 bymeans of a pin 8. The bar 7 is provided with a casing 9 at its lower endwhich carries said pin and incloses the end of the bar 4. In this mannerthere are no projecting ends to catch in the clothing of pedestrianswhen the gate is being moved. The bar 7 engages with a recess 10 formedin the end of the beam 3 and a strap 11 holds the bar in said recesswhile permitting free movement of the parts. The end of the beam 3 isconnected with the end of the beam 3 of the other gate by means of acable 12 which passes through an eye 13 carried at the top of the post.This cable is of such a length that it will hold one gate in raisedposition while the other gate is in lowered position. The bar 7 is ofsufficient length as to remain in engagement with the strap 11 andrecess 10 when the beam 3 is in vertical position, as shown in Fig. 2.When the gate is in lowered position the end of the beam engages thecentral part of said bar 7 as shown in Fig. 1. It will be seen from thisfigure that the beam 3, the cable 12 and the rods 4 and 7 form a barrieror gate of such a form as to render it difficult for a person to attemptto go through or over it.

The operating means for the gates consists of a centrally locatedstandard 14: having its lower end in engagement with a socket 15 formedin the bottomof a chamber 16 made in the street at the central part ofthe intersection of one street with the other, said chamber being closedby a cover 17 This cover has an opening therein through which thestandard passes and said standard is provided with a handle 18 by whichan operator, preferably a crossing policeman, may rotate said standard.The standard has secured thereto a cable operating device 19 which islocated within the chamber. This device is composed of two sections 20and 21, one located above the other and having their ends of arcuateshape. The ends of each section are curved in different directions andthe curves of the two sections are reversely arranged as clearly shownin Fig. 7. A pair of cables indicated at 22 are secured to each sectionandthese cables engage the curved ends,

said ends being preferably grooved to receive the cables. As shown in F1g. 7 the cables are secured adjacent the inner end of .each curve sothat the cable passes oft the high part of the curve. Conduits 23 arelocated under the streets and extend from a point adjacent one post to apoint adjacent the adjacent posts and these four conduits are eachconnected midway of its ends with the chamber 16 by means of theconduits 24. The four cables 22 pass from the member 19 over suitablerollers 25 into conduits 24. Each cable is connected with a pair ofcables 25 which pass over suitable pulleys into the conduit 23 wheresaid cables. extend in opposite directions and have their ends securedto the gates so that the rotation of the member 19 will cause saidcables to operate the gates. As shown in Fig. 1 the end of the cableafter passing through an adjustable member 26 of curved shape carried bythe end of the beam 3 is removably secured to an eye 27, carried by thebolt 6, by means of a snap hook 28 secured on the end of the cable. Themember 26 is provided with a plurality of holes by means of which it maybe adjusted to any position on the beam 3. By this means the inclinationof the cable 25 in respectto the beam 8 may be changed so as to renderit possible for said cable to raise the beam at all times thuspermitting the extent of movement of said beam to be varied. By thearrangement of the cables on the curved ends of the actuating member 19it will be ,seen that the cable connected with the gate being raisedwill have suflicient slack to prevent this cable operating against thecable taken up by the corresponding end of the other section of thedevice.

I prefer to provide electric alarms 29, one located on each post, andlocated in a circuit including a battery 30 and switch 31, said switchbeing located within easy reach of the operator of the device.

It will be seen that the device is operated by the usual crossingpoliceman stationed at the intersection of the streets and the standard14 may contain the usual semaphore arrangement for controlling thestreet traffic so that when the said semaphore is set to stop traflicalong one street the gates will be lowered across the side-walks of thisstreet to prevent pedestrians from crossing the street, the vehicles onwhich have been given the signal to cross. For instance when the member1 1' has been turned to place the semaphore in position to give thevehicles on street A the right of way, the operating device 19 willoperate the cables to lower the gates 3 across the edges of the curb. onstreet A so as to prevent pedestrians from crossing said street A. Atthe same time gates 3 Will be raised to permit the pedestrians to crossstreet B. v

It is thought from the foregoing'description that the advantages andnovel features of my invention will be readily apparent.
